“快乐的罗杰”英文全称

叫做Jolly Roger
The Jolly Roger is the name now given to any of various flags flown to identify a ship's crew as pirates. The most famous Jolly Roger today is the Skull and Crossbones, a skull over two long bones set in an X arrangement on a black field. Historically, the flag was flown to induce pirates' victims to surrender readily.

Since the decline of piracy, various military units have used the Jolly Roger, usually in skull-and-crossbones design, as a unit identification insignia or a victory flag to ascribe to themselves the proverbial ferocity and toughness of pirates.
